JOSEPH M. DAWES, OF OWEGO, NEW YORK.

SKID.

SPECIFICATION forming part of Letters Patent No. 328,571, dated October 20, 1885.

Application filed August 29, 1885. Serial No. 175,664. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH M. Dawns, a citizen of the United States, residing at Owego, in the county of Tioga and State of New York, have invented certain new and useful Improvements in Skids; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a perspective view of my invention, and Fig. 2 a cross-section taken on line a: :0 thereof.

The present invention has relation to certain new and useful improvements in skids for raising and lowering heavy bodies; and it consists in the several details of construction, substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A represents the tracks, grooved upon their inner sides, as shown, said tracks being connected together at their ends by transverse braces a. The upper one of the braces a has a slot in which is located a grooved pulley, b, and around this pulley passes a cord or rope, 0. One end of the rope 0 is suitably connected to a carriage, B, and extends around a grooved pulley, d,

3c journaled in a slot formed in the upper oneof the cross-braces of said carriage, and thence up through the slot in thebrace a within reach of the attendant. The side bars, 6, of the carriage B are formed with grooves to correspond with the grooves in the tracks A, so that they will fit and overlap each other, as shown more clearly in Fig. 2. Asimple tongue and groove were the usual means of connecting the carriage and tracks together, the tongues on the side bars of the carriage entering the grooves on the tracks. This was not sufficient for the heavy weight being moved, and would frequently split or break the tongues, from the great pressure thereon, which I have entirely overcome by the construction herein described.

The carriage B is provided with braces O, pivoted at one end to the inner sides of the bars 6, and their opposite ends pivoted to levers D, connected near their upper ends by transverse brace f. The braces C have re movable stakes g to prevent the weight being moved from sliding against the levers D, said levers at their lower end having friction-rollers h, which bearagainst stops 2' on the lower ends of the grooved side bars, 6.

WVhen in position, as shown 1n full lines, Fig. 1, the weight to be moved rests upon the braces O, the stakes g preventing the weight from bearing against the levers D. The carriage with its load is lowered in the usual manner, the stakes being Withdrawn and the braces and levers brought to the pos1t1on,as shown in dotted lines. In this position the lower ends of the levers rest on the floor and form a bridge for the box or other article to slide to the floor.

In moving heavy weights the rollers on the ends of the levers greatly assist in bringing them in position to form a bridge.

In loading it should be understood that the carriage is at the top of the tracks and on a level with the floor; also, when elevating the load and unloading, at the top.

The device may be used for removing art1- cles from one floor to another, whether laid on the stairs or placed from a window to the ground; and it is equally applicablein all places where a support for the tracks can be found to form an incline plane.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a skid, the combination, with the grooved tracks, of a carriage engaging with the grooves therein, a cord or rope for operating the carriage, levers provided with handles, and braces pivoted thereto and to the carriage, said braces having removable stakes, substantially as and for the purpose set forth.

2. In a skid, the combination, with the carriage thereof, of pivoted braces and pivoted levers having at their lower ends rollers, substantially as and for the purpose specified.

3. A skid consisting of grooved tracks, a carriage having grooved side bars, pivoted braces provided with removable stakes, and pivoted levers having rollers at their ends, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOSEPH M. DAWES.
